Ensure that reading config log on rebalance doesn't hang the herder

> Project: Kafka
> Issue Type: Bug
> Reporter: Gwen Shapira
>
> Right now, the handleRebalance code calls readConfigToEnd with timeout of
> MAX_INT if it isn't the leader.
> The normal workerSyncTimeoutMs is probably sufficient.
> At least this allows a worker to time-out, get back to the tick() loop and
> check the "stopping" flag to see if it should shut down, to prevent it from
> hanging forever.
> It doesn't resolve the question of what we should do with a worker that
> repeatedly fails to read configuration.
